I don't know if it matters in this case or not but on WinXP I had a problem with spaces in paths. If I put OSG into a directly with a space in it and then added that directory to my path: I would be able to run osgviewer.exe but it would fail to find any of the DLLs. Moving it to a directory without a space fixed it.
At the time, I couldn't find anything to make it work... but I didn't try very hard either (since I had a work-around). It seemed like DLL resolution was done differently than exe path resolution. I could have been out of my mind, too. -Paul Mike Weiblen wrote: > Interesting, thanks for the data.
